Burying hair

Q:

1. Must the hairs that collect on the comb/brush be buried?

2. Must the hairs that fall out when combining/brushing the hair be collected and buried?

3. Must the hair removed from the eyebrows, nose, mustache, chest, legs, etc. all be buried?

4. When having a shower/bath, hairs that fall off sometimes tangle up together around the drain. Must this be buried?

Uni-brow

Q: I have a uni-brow and I want to remove it but my parents say we need an authentic hadeeth or quranic ayah.
